Okay. This could be an ABS issue but in this case the ABS is simple so don't let it confuse you. Basically, all it does is pressurize the fluid in a hard breaking situation so if you removed the master then the ABS should not need to be bleed using a scan tool so let's not worry about that for now.
When you bench bled the unit did you use clear lines to route back to the reservoir so that you can confirm you actually had fluid movement out of each port?
There is a chance that the master is the issue.
At this point, I would suggest we remove the lines and route them back and bleed it again just to confirm the master is sending fluid. Then we may have to disconnect the rear lines and check for obstructions. You have multiple connection points so we may need to look for a leak as well, but I suspect you would have found that.
